These
Level Sets include a great variety of levels. Some may have
levels that are extremely difficult, some may finish themselves with no user interaction, and some may have dozens of rings on a single level.

A long time ago, I made a set called Aqua Adventure. Now, here is a sequel that I hope you all enjoy. It takes place in underwater environments and you'll use custom PUs and learn interesting facts about the ocean and sea creatures. So, bash your way through 40 levels of splish-splashing fun!
